Web APIs are increasingly becoming an integral part of web or mobile applications. As a consequence, performance characteristics and availability of the APIs used directly impact the user experience of end users. Still, quality of web APIs is largely ignored and simply assumed to be su ciently good and stable. Especially considering geo-mobility of today’s client devices, this can lead to negat...

The Gene Expression Omnibus or NCBI GEO (http://www.ncbi.nlm.nih.gov/projects/geo/) is one of the most comprehensive public repositories of microarray data. The data in NCBI GEO is organized into samples, series, datasets and platforms. Platform files specify the characteristics of a particular type of microarray chip, including a mapping of chip features to genetic features. These mappings are...

BACKGROUND To reduce the number of non-geocoded cases researchers and organizations sometimes include cases geocoded to postal code centroids along with cases geocoded with the greater precision of a full street address. Some analysts then use the postal code to assign information to the cases from finer-level geographies such as a census tract. Assignment is commonly completed using either a p...

Graphite and graphene oxides have been studied amply in the last decade, due to their diverse properties and possible applications. Recently, their functionality as photocatalytic materials in water splitting was reported. Research in these materials is increasing due to their band gap values around 1.8-4 eV, and therefore, these are comparable with other photocatalysts currently used in hetero...

Purpose: Development of new building materials with improved exploitational properties allowing to isolate various nature waste. Methods: Chemical methods analysis; experimental research in laboratory conditions; physical-mechanical methods, statistical methods. Results: New material, possessing geo-protective properties, has been obtained which contains outgoing oily paper filters formed durin...

The arrival of a negative customer to a queueing system causes one ordinary customer to be removed (or killed) if any is present. The arrival of a disaster, on the other hand, kills all the customers in the system if any. In this paper, we extend the queueing theory on negative arrivals and disasters to the discrete-time Geo=Geo=1 queueing system. Speci2cally, we 2nd the ergodicity condition an...

The widespread proliferation of location-acquisition techniques and GPS -embedded mobile devices resulted in the generation of geo-tagged data at unprecedented scale and have essentially enhanced the user experience in locationbased services associated with social networks. Such locationbased social networks allow people to record and share their location and are a rich source of information wh...

Vehicular routing has been an extremely active research field in recent years with geo-routing protocols typically favoured over conventional topology based routing protocols due to their advantages in terms of scalability and lower overhead. Before a geo-routing protocol can transmit a packet, it must be aware of the position of the target node and is reliant upon a location service to supply ...
